" EMERGENCY-BRAKE non sH IPs.

To all whom it may concern.

Be it known that I. FREDERICK A. Mns'rn, a citizen of the United States, residing at Baltimore, in the State ofsMaryland, have invented new and useful Improvements in Emergency-Brakes for Ships, of which the followingis a specification.

This invention relates to a combined emergency brake and rudder for marine vessels; the object of the invention being to provide means of the class referred to whereby a vessel may be quickly stopped or steered to one sideor the other as may be required in case the usual rudder of the ves-' selshould become useless or lost, the combined 'rudder and brake being operable from the bridge oflthe vessel and being easily runs of the cables.

controlled from such point.

' With the above and other objects in View the invention consists in the novel construction, combination and arrangement of parts as Will be hereinafter more fully described,

illustrated and claimed.

In the accompanying drawings :Figure 1 is a side elevation of a portionof a vessel showing the device of this invention applied thereto. Fig. 2 is a horizontal section through one side of the same showing the hinged plate closedin full lines and open in dotted lines. Fig. 3 is a detail vertical cross section through the guide ways at one side of the vessel. Fig. 4 is a diagrannnatic plan view illustrating the windlasses and the I Fig. dis a detail perspective viewof one of the latch rods.

Referringto the drawings A generally designates the hull of a marine vessel. Ar-

ranged at opposite sides thereof are hinged plates 1 each of. which is hinged along its rear vertical edge to the hull as shown at 2, leaving the opposite or forward edge free to swing rearwardly' to enable the a plate to serve either as an emergency rudder or brake for arresting the forward progress of the vessel. I

Each plate is provided at its forward edge with eyes or knuckles 3 and in the preferred embodiment of the invention these eyes or knuckles are formed on the forward extremities of substantially horizontal straps 4 which are riveted or otherwise fixedly secured to the adjacent plate 1, said straps extending entirely across the plate and being provided at their rear extremities with other knuckles or eyes 5 to receive the hinge pins 2.

Speoificationof Letters Patent.

Application filed m 1, 1914. Serial No. 848.433.

Journaled in the eyes or knuckles 3 of each plate 1 isa latch rod 6 provided at its top and bottom extremities with hooks or fingers 7 which are adapted to en age keepers Son the hull of the vessel for the purpose of locking the plate in its closed position, in which position it lies broadside against'the hull of the vessel and conforms to the shape thereof so as not to interfere with the movement of the vessel through the water.

Each of the latch rods is'provided with two arms 9 and 10 through both of which passes a flexible cable 11 having stops 12 and 13 thereon, said cable passing through eyes in said arms so that the stops referred to may come in contact with said arms for the purpose of rocking the latch rod in one direction or the othe'r in accordance with the direction in which the cable is moved. There are two cables employed for operating the two latch rods and plates 1 and in connection. with said cables, separate and independent windlasses 14c and 1 5 are employed, the samebeing mounted by preference on the bridge 16 of the vessel where the pilot stands so that he may instantly release oneor both of the plates. Each cable runs through suitable fair leaders 17 and over direction pulleys or sheaves 18 and is wound in opposite directions around the drumof its respective windlass so that the operator may turnthe windlass in one direction to operate the latch rod and release the combined brake and rudder or by turning said windlass in the opposite direction he may restore said combined rudder and brake to its closed positionand at the same time lock it by means of the latch rod. There is sufficient frictional engagement between the latch rod 6 and the eyes 3 to prevent the turning of'saidlatch'rod until the plate 1 has come in contact with the hold of the vessel when by pulling on the cable and overcoming said frictional resistance, the fingers 7 arecaused to engage the keepers 8. It will be understood that the closing of the plate 1 is eflected while the vesselis at a standstill and the closing of'the plate without the operationof the latch rod may be insured by reversing the propeller and backing the vessel so that the current of water cable thus controls each of the plates to the strain on the plateandprevent the :same

from being twisted or bent by the actionof the water. Each of saidstay rods is pro yided-at its forward extremity with runner 20 which is movable in a fore-and aft direction in a slotted guide shown :as

formed by tWo parallel flanged plates 22 ;and 28 fixedly secured to the side of theyessel. The lerngth of the stay rods is preferably 1-. suchas tostop the rearward movement of t he adjacent plate l when the latter stands in a position about perpendictilar to the longitudinal .axis of the Vessel. Y

The windlasses may :be .operatedeithermotiiiepower :orhand power as may be preferred. As soon .as thewin'dlasses areftlllined in the. proper direction, the pl ates are nn latched and are thereupon caught by the Water and swung .to their w nki position where they act to quickly check .th'efor w ard progress ,of the vessel. In case the rudder becomes lost or the steeringjgear-ggets out of order, the pilot may release .thecplate ,1 either on the starboard orpert side of ,the

vessel for'the purpose ofst'eeringthe 'x essel to starboard or por't as may be 'necessary at .the time. v The mechanism referred tofthns acts'bot'h as an emergency rudderand, as .a

bra kejyand is under the immediate ,c'ontrol of the .pilot or his assistant.on'theibridge of the Vessel. V

n addition to the controlling meansi -here nabove described, it maybe found desirable in someca'ses to provide jtherunners 20 avi't'h I rackbars 24 as shown in Figs. 1 and 2, sa'id rack bars meshing with pinions j25 on shafts 26 located at opposite siilcles 'ofrtheihnll -and j ournaledflin .bear'ingsjQ'Z thereon. ,The shafts 26fmay be controlled by any fsiiitajble means to provide for the rotation thereof and this way h mergency r d e sqmay b r openedand closed to any desiredextent out permitting them to spring si ddenlyopen V to their full extent.
